SEPARATOR AND AMALGAMATOIR.

Application filed February 10, 1916.

To all whom 2'25 may concern: I

Be it known that I, ADoLPH P. PALMER, a citizen of the United States, residing at Oakland, in the county of Alameda and State of Galifornia, have invented new and useful Improvements in Separators and Amalgamators, of which the following is a specification.

lhis invention relates to an apparatus which is especially designed for separating gold from sand or lighter material with which it may be mixed or associated.

It consists of a vertical main frame having a central, vertical shaft and a surrounding sleeve independently driven at different rates of speed, one of said driven members carrying a cylindrical chamber, and the other carrying a pan revoluble within said chamber, the inner cylindrical sides of which are grooved or channeled to carry a body of mercury, and a rotary member having openings through the lower portion and spiral flanges around the upper portion is carried so as to extend into the second cupshaped member. Interiorly of the revoluble members is a stationary chute with connections by which material to be treated is delivered into the inner pan;thence passing out through the perforated, spirally grooved rotary member the material is thrown into contact with the mercury containing channel and thence continues to flow upwardly around and between the spiral channels which maintain it in contact with the mercury lined cylinder, after which it dis charges into the outer chamber of the frame and thence downwardly through openings in the bottom thereof.

It also comprises details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a vertical paratus.

Fig. 2 is a horizontal cross-section on line 22 of Fig. 1.

Fig. 3 is a detail elevation of the revoluble table.

As shown, this apparatus consists of a rigid frame A, which may be made of cast iron, or otherwise. lnteriorly to this frame is a cylindrical-shaped receiver B, which may be fixed in place by means of a bearing or brace C and bolts 2 connecting it with the. exterior portion of the frame. From the upper part of this receiver B an annular section of the ap- Specification of Letters Patent.

space while the m Patented June 26, 191?. Serial No. 77,384.

' plate 3 extends inwardly, being bolted to the upper part of the receiver B, and its inner periphery carries a downwardly extending cylindrical chute st, the lower end of which is made open and convergent.

Centrally through this structure extends a shaft 5, turnable in bearings, as at 6. Surrounding this shaft and independently revoluble thereon is a sleeve 7 turnable in bearings 8 which surround the inner shaft. 9 is a cylindrical fastening, open at the upper end and having a se mental bowl-shaped bottom 9"; and above this bottom and around the cylindrical portion of the chamher is a depression or groove 10 so that with centrifugal action any mercury in the bowl 9 will be carried to the groove and, thus, all the mercury will be retained in a definite achine is in operation. This cylindrical chamber is secured to the inner shaft 5, below the end of the sleeve 8, and be driven at a velocity of 2000 revolutions per minute.

Upon the lower end of the sleeve 7 is fixed 'a pan or saucer-shapedtable 11; the sleeve being revoluble chute 4. From the bottom convergent end of this chute the material drops into the revoluble table 11 and by centrifugal action is thrown outwardly through holes in a sur rounding cylinder 15. This cylinder is secured to and carried by the pan exteriorly to the chute 4.- and above the perforations in the lower end, it has spiral flanges 16 which extend outwardly, and this device, located within the outer cylinder 9, forms an annular passage through which the material thrown centrifugally through the holes in the member 15 will be caused to impinge against the mercury contained in the channel 10.

The centrifugal force and revolution of the cylindrical member 9 causes any mercury which may be contained in the bowl Ii 1 between portion 9 to move up into this channel and any surplus will be distributed along the inner face of the chamber which has lip or flange at the top, as shown at 17, to arrest any mercury, which may'have arisen along the cylinder, from escaping. It also serves to retain any platinum which may be associated with the other material. The lighterless valuable portions which will not amalgamate, will be carried up through the chanthe members 9 and 15 and; the spiral flanges 16 will act to cause a spiral rotation and upward discharge. of the pulp, which, passing out over. the flange at the. top oi? the cylinder 9, will be delivered into the cylindrical receiver 13 iirom which it passes downward and outwardly through screened openings l8 at the bottom,

The ii ner shaft may be hollow, as shown in, dotted lines in Fig. 1 and have a cap, as at 19, at each end. Means are provided, as shown at 20, for the vertical adjustment of the shaft and the, cylinder and pan.

lgV ien the revolution of the pan and bowl stop the centrifugal flow of material will cease, and any mercury remaining 1511 the channeLlO or the. cylinder will gravitate; into the bowl 9 and will pass thence tlu'ough holes 21 leading through the sides of the shaft to. the interior.
